Distribution In the 1976-1986 period Diastylis rathkei was mainly found in the eastern coastal zone. In this area the species reached a high distribution frequency and its maximum densities (70 ind./m2). In the 1994-2001 period the species was also found outside this area near the Hinder Banks, but its distribution frequency decreased and its maximum density dropped to 30 ind./m2. [details]

Description Cumaceans with a thickened head-thorax part and a slender abdomen. Up to 9 mm long. [details]

Distribution In the 1976-1986 period Diastylis rathkei was mainly found in the eastern coastal zone. In this area the species reached a high distribution frequency and its maximum densities (70 ind./m2). In the 1994-2001 period the species was also found outside this area near the Hinder Banks, but its distribution frequency decreased and its maximum density dropped to 30 ind./m2. [details]

Habitat Diastylis rathkei has a clear preference for fine-grained sediments as the relative occurrence exceeds 60% in sediments with a median grain size of 50-100 μm. Although the species occurs in sediments with both high and low mud contents, D. rathkei reaches a maximum relative occurrence (> 20%) in sediments with a mud content exceeding 20%. [details]
